VALVE son THERAPEUTIC APPARATUS.

Specification 61: Letters Patent.

Application filed August 18,1910. Serial No. 577,794.

Patented To all whom it may concern Be it .known that I, JOSEPH B. FEY,a citizen of the United States of America, residing at Akron, in thecounty of Summit and State of Ohio, have invented certain v new anduseful Improvements in Valvesfor Therapeutic Apparatus; and I herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which ,itpertains to make and use thesame.

This invention relates to improvements in therapeutic apparatus andespecially to that class of apparatus designed to produce air currentsfor operating massage devices,

Sprayers, atomizer-s and'the like.

. The object of this invention is to provide in connection with suchapparatus means for positively controlling and directing the aircurrents produced by the operation of said apparatus.

My invention therefore consists in providing in connection with a fluidsystem a new and improved rotary valve.

Myinvention also consists in the features of construction andcombinations of parts described in the specification, pointed out in theclaims and illustrated in the accompanying drawings.

In the accompanying drawings, Figure 1 is a central vertical section ofan apparatus embodying my invention. Fig. 2 is a section on line 22,Figrlf Fig. 3 is a section on line 33, Fig. 1. V

Again referring to the drawings, 2 represents a motor which may bedriven by electricity or any other suit-able motive power, and as shownthe motor is mounted on a platform or support 6, and on said platform inproximity to said motor is mounted a cylinder 7 which is provided withan airoutlet 8 and around the said outlet is arranged a screw threadedboss '9. 'In the cylinder 7 'is arranged a piston 10 having acup-leather packing 11 the arrangement of which is such that when thepiston is forced down into the cylinder the air therein will tacle orair tank 15 having an openin in the bottom thereof which is closed y abe forced out through the air outlet 8 and when the piston is drawnoutwardly in the cylinder the said cylinder will fill with air.

The piston 10 is operatively connected with a pin 12 eccentricallymounted on the drive shaft 13of the motor by a piston rod 14:.

Below the platform 6 is arranged a recepand at one side of thereceptacle 15 is ar- Aug.1f.2, 1913.

screw threaded stopper 17, ,Near the top ranged a valve casing 18 whichis preferably formed integral with the said receptacle 15. In the wallof the receptacle 15 are arranged passageways l9 and 20. The,

passageway 19 at its upper end communicates with the interior of saidvalve-casing 18 and atits lower end with the interior of the saidreceptacle 15, and the passa eway 2 0 communicates at its upper end witsaid valve casing 18 and at its'lower end with the I outer air, and atits lower end the wall of sa d passageway 20 is provided with anexterior screw thread. The valve casing 18 is.

.also provided with an openin 21 around which is fQrmedascreW threa edextension 22 whichv screws into the boss 9 on the bot-' tom of thecylinder 7, and the said valve casing 18 is also provided with anopening 23 which communicates with the receptacle 15. Within the'valvecasing 18 is mounted a rotatable plug valve 24 which is preferablyprovided with a valve stem 25 by means of which it may be readilyrotated. The said valve 24 is provided with passageways 26 and 27 whichextend diametrically through said valve, and the said passagewaysinterspot with each other at the center of the valve. The passageway 26at one end is enlolrged, as shown at 28, and therein is formed a valveseat 29. On the valve seat 29 is arranged a valve 30. On the perimeterof the valve 24 is formed a groove 31 which also forms a passageway aswill appear later.

To the screw threaded end of the passageway 20 is secured a flexiblehose 32 which is provided with a nozzle 33 having a valve 34. The saidnozzle 33 is provided with a tapered end onwhich any suitable massagedevice, sprayer, atomizer 'or thelike may be mounted.

The operation of the embodiment of my invention shown in theaccompanying drawing is as follows: If it is desired to secure acontinuous stream or How of air, such as would be desirable inconnection with a sraying device, the valve 24 is turned to the positionshown in Fig. 1, in which po- -sition the valved end of the passageway26 will register with the inlet-opening 23 of the receptacle. 15 and theopposite end of said passageway 26 will register with the outlet opening8 of the cylinder 7. Also the groove 31. willspan the ends of thepassageways 19 and 20. Therefore when the piston is operated the air inthe cylinder 7 will be forced down through the passageway '26 intothe'receptacle on the downward stroke of said piston. and will pass upthrough the passageway 19 into the valve casing 18, then through thegroove 31 in the valve 24 and do'wn'the passageway 20 to the hose 32 andout through the nozzle 33. Now as the area of the inlet 23 to thenozzle;

. piston is operate receptacle 15 is greater than the area of the.outlet of the nozzle more air will be forced into the receptacle 15than can escape during .the downward movement of the piston 10, but onthe upward movement of the piston the valve 30 will close preventing theair in'thev receptacle 15 from being drawn back into the cylinder 7 andtherefore the .air will continue to flow out of the nozzle during theupward stroke of the piston. It is therefore possible to produce aconstant and uninterrupted flow of air through the If it is desired .toproduce an intermittent flow of air, such as might be utilized inoperatlnga massage device, the

valve 24 is turned so that one end of the passageway 27 reglsters withthe outlet 8 of the cylinder 7 and the other end of said passagewayregisters with the passageway 20. In this position the valve24 willclose" the. inlet opening 23 to the receptacle 15 and also the pnssa way19. Then when the into the "cylinder theair will be driven directlythrough the assageway 27, the pasthe nozzle 33,

20'and the ose 32 and out through I but on the up stroke of the pistonthe air will be drawn back into the sageway cylinder producing a vacuumor suction in the nozzle 33.-

equipped to serve. as an ozonizer or as adisinfectant chamber.
